Asplenium flaccidum is a species of fern in the family Aspleniaceae. The plant common name is drooping spleenwort or weeping spleenwort, and the species name flaccidum derives from the Latin root meaning drooping.[1] An example occurrence of A. flaccidum is within a Nothofagus-Podocarp forest at Hamilton Ecological District on New Zealand's North Island in association with other fern species understory plants, crown fern, Blechnum discolor being an example.[2]

Taxonomy
editA global phylogeny of Asplenium published in 2020 divided the genus into eleven clades,[3] which were given informal names pending further taxonomic study. A. flaccidum belongs to the "Neottopteris clade", members of which generally have somewhat leathery leaf tissue. It forms a clade with A. appendiculatum and A. chathamense.[4]
